UNITED STATEl CHARLES J PEMBROKE, OF ROCHESTER, NEW YORK;

VEHICLE FRAMEi Specification of Letters Patent. Application filed September 10, 1907. Serial No. 392,109.

Patented Oct. 20, 1908.

To all whom it may concern." Be it known that I, CHARLES J. PEM- BROKE, of Rochester, in the county of Mel".-

- scription of the same, reference being had to theaccompanymg drawings, forming a part of the specification, and to the reference-numerals marked thereon.

The present invention relates to vehicle frames-of the type in which a main yieldingly supported frame carries a supplemental frame in a manner to' permit the latter to yield independently thereof in order to prevent sudden. shocks being transmitted to the occupants of the vehicle, and it has for an ob'ect to provide a yielding support which will give a perfectly balanced action, and which may be manipulated from'the vehicle without inconvenience. v

' To these and other ends the invention con sists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure l is a side elevation of a motor vehicle embodying my invention, parts being broken away, and Fig. .2 is a view of the rear end of the vehicle frame.

Similar reference numerals in the several figures indicate similar parts.

' In the present embodiment of my inven tion there is employed a main frame 1 yieldin ly supported at the front and the rear on ax es 2 and 3 by springs 4 and 5 respectively.

tected by the seat carrying frame.

The main frame 1 carries a supplemental or seat carrying frame 6 which is guided on the outer side of the main frame by having its side pieces 7 located beyond the side pieces 8 of the latter and is pivoted to thd side pieces 8 at its forward end at 9. In this manner the side pieces do not appear conspicuous and are arranged so as to be pro- Located at the rear of the seat carrying frame is the yielding support of the latter,

y a U-shapedpiece 11 and the pieces or frames 10 and 11 are connectedbya plurality of vertically arran ed parallel coil springs 12, which serve to yiel the seat carrying frame in a perfectly balanced manner. In order that these springs 12 when broken or otherwise inefiecti've may be removed for the purpose of replacing them by others, the hooks or eyes 13 and 14 which secure the ends of the springs to the main and to the supplemental frame are open, while for the purpose of adjusting the tension. of the springs the' hooks 13 are adjustably connected to the frame 10 as by being passed through perforations in the latter and enga ed by thumbnuts 15. Y

tis apparent that by arranging the adjusting devices for the yielding support in an elevated position in the rear of the seat carrying frame, or in other words at the upper ends ofthe coil springs the occupants of the vehicle may adjust the tension on the springs to suit the road over which they are traveling, without being compelled to leave the vehicle. a

Of course the form ofthe springs, the construction of the adjusting devices therefor and other parts may be changed without departing from the spirit of this invention.

I claim as my invention:

1. In a vehicle frame, the combination with a yieldingly supported main frame, having an upwardly projecting frame at the rear thereof, of a seat carrying frame pivotally mounted at its front end and yieldingly suspended at its rear from the upwardly proj ecting frame.

. 2. In a vehicle; frame, the combination with a yieldingly supported main frame, of a seat carrying frame pivotally connected at its forward end to the main frame and aplurality of vertically arranged parallel coil springs arranged in rear of and suspending t e rear of the seat carrying frame from the mainframe.

3. In a' vehicle frame, the combination with a main frame having longitudinal side pieces, of a seat carrying frame having longitudinal side pieces pivoted at their forward ends and arranged on the-outside and in a horizontal plane with the side pieces of the .main frame, and a yielding su port for the rear end'of the seat carrying rame carried by the main frame.

4. In a vehicle frame, the combination 'with a main frame having an upwardly extending frame at the rear thereof, of a seat dingly support or'suspend carrying frame pivotally sup ,)orted on the main frame, and adjustable yielding devices connecting the upwardly extending frame and the rear end of the seat carrying frame.

5. In a vehicle frame, the combination with a main frame having an upwardly extending frame at the rear thereof, of a seat carrying frame pivotally mounted on the main frame, a series of parallel coil springs connecting the upwardly extending frame and the seat carrying frame, and devices for adjusting the tension of the springs arranged at the upper ends of the latter.

6. In a vehicle frame, the combination with a main frame having an upwardly extending inverted U-shaped frame arranged transversely thereof, of a seat carrying frame pivotally supported on the main frame, and a series of parallel coil springs connecting the U-shaped frame and the seat frame.

7. In a vehicle frame, the combination with a main frame having an upwardly expieces and an upwardly extending inverted U-shaped frameconnecting the side pieces, of a seat carrying frame having longltudmal side pieces pivotally supported on the outer sides of the longitudinal pieces of the main frame, and a series of vertically arrangeg coil springs supporting the seat carryin frame from the U-shaped frame.
